Description

[Detailed explanation of the idea] The present invention relates to a support for a long heavy object.

More specifically, the present invention relates to a support for a long heavy object that can firmly support the long heavy object by simply placing it thereon, and that can also rotate the long heavy object in a circular motion.

Conventionally, when rotatably supporting a long heavy object with a complicated shape for processing, a special jig was used to support it rotatably, or during rotating work, it was stably supported and rotated. I needed to do it.

This resulted in poor work efficiency and required skill to detect a safe and stable support point.

The present invention was developed in view of the previous points, and its gist is that a guide wheel is rotatably arranged on a pedestal with standing legs, and a ring-shaped string-like body is connected between the guide wheels. This is a support for a long heavy object made by rolling it up, and its purpose is: ■ It has a simple structure and can reliably support a long heavy object in a rotatable manner, and ■ It has a special structure. To provide a support tool for a long heavy object that can be easily handled by anyone without requiring special skill, thereby improving the efficiency of supporting work for long and heavy objects.

Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes an annular string-like body, such as a wire, which has sufficient strength and flexibility to support a long and heavy object.

Next, 2 and 2' are guide wheels, which in this example are pulleys, and are rotatably mounted on a pedestal 5 on which legs are placed at appropriate intervals. An annular wire 1 is wound on J-2 and 2'.

The adjustment wheel for adjusting the slack of the wire 1, in this example, the pulley 4, is placed at the center of the bottom between the Boo 'J-2 and 2', and the pulley 4 changes its placement position up and down in the figure. It is now possible to do so.

Next, 3 is a supported object, which in this example is designated as H steel.

Next, the operation will be explained based on the above configuration.

First, the supported object 3 is placed on the wire 1 between the pulleys 2 and 2'.

At this time, if the wire 1 is given an appropriate amount of slack, the weight of the object to be supported 30 will tension the wire 1 into a substantially V-shape, causing the above-mentioned Boo! The object to be supported 3 is supported at a substantially intermediate position between j-2 and 2'.

At this time, the lowest point of the supported object 3 is indicated as A in the figure.

If the supported object 3 is now rotated in this state using a rotating support (not shown), the lowest point A will also rotate, but the wire 1 in contact with this lowest point A will be connected to the pulley 2.2.
'.

Since it is movably supported by 4, it moves together.

Therefore, compared to the case where the lowest point A moves along the wire, the friction is smaller and the supported object rotates 30 times more smoothly.

Furthermore, since the wire 1 is flexible, it supports a plurality of lower parts of the object 3, unlike the wire 1 which supports only one point AO at the lowest point of the object 3, thereby achieving safe and stable rotation.

Note that a belt may be used instead of the wire 1 used as the button in this embodiment.

Furthermore, a chain may be used instead of the wire 1, but in this case, sprockets are used instead of the pulleys 2, 2', and 4.

Furthermore, by setting the size of the pedestal 5 and the sizes of the pulleys 2, 2', 4, etc. according to the size of the object 3 to be supported, it is possible to make the support for a long heavy object even easier to handle. .

As described in detail above, the present invention has the guide wheels 2, 2' rotatably disposed on the pedestal 5, and the guide wheels 2, 2'
It is a support for a long heavy object made by winding an annular string-like body 1 between 2' and 2'.A guide wheel 2 rotatably arranged.
, 2' has a simple structure in which a string-like body is wound between the guide wheels 2 and 2', and yet it can reliably support a long heavy object in a rotatable manner. Supported object 3 on the body
This tool can be easily handled by anyone without any special skill, as all you have to do is place the object on top of the object. It has various advantages such as:
